Powerbuilder 12.5 Classic

hi,

i got a PB classinc .Net Assenbly that generate a pdf file from a dataStore.

This Assembly is added as reference in a ASP.NET MVC 4 web application.

In my PC with IIS Express (from VS 2012) it works perfectly but when i try to run into production server (Windows Server 2012R2)  it returns an error message:

[InvalidOperationException: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.]
System.Windows.Forms.MessageBox.ShowCore(IWin32Window owner, String text, String caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, MessageBoxOptions options, Boolean showHelp) +2962140
   c__rareports.InitAssembly() +293
   MyApp.Reports.RAReports..ctor() +12

In my assembly there's not any messagebox, code from .net app:

 RAReports report = new RAReports();
 report.GetReportFile(paramssss...);

Dll and PBD generated are in bin.

Aby idea about this error?

thanks in Advance

HI Mariano;

      My first guess is that your Assembly does not have the same privileges in the production environment to access the GhostScript (I assume that is what you are using for PDF generation) printer.

I think that error goes just when in asp.net code i initialize assembly, then pile goes to:



c__rareports.InitAssembly()



And then throw error message

Hi Mariano;

   Andres brings up a great point. Note that you'll need the PB .Net run-time and not the native PB run-time, as follows:

 

Note: The PB .NET Run-time is a separate MSI file in PB 2017 and not located in the Packager.

Regards ... Chris
